Pipe System - Flow Calcs - Tie Ins
Pipe System - Flow Calcs - Tie Ins
(OP)
I am wondering if anyone has either a good reference (by good I mean more practical than theoretical) regarding calculating flow rates in new additions to existing pipe networks. Would also appreciate a couple of key thoughts or general attack steps in how something like this could be analyzed.
For example, if you worked in a large plant with a massive pipe network, how could you go about finding out what the potential flow rate would be if you tied into some point in that line and added a new branch? It would be very cumbersome to re-analyze the whole network. Is there a way to take some key characteristics (existing pressure and flow) at the location where you want to tie in and use these along with a calculated system curve to determine an operating point?

No, calculation of network flowrates is not all that cumbersome and having a developed computer model of a large multi-million dollar system is a reasonable thing to do.
We have junior engineers in our company performing exactly this task.
Computer software such as AFT Fathom takes the drudgery out of the calculations, IMHO
